That'll take a long time.

Since the vaccines are excellent at preventing serious outcomes, a fairly large share of the infected won't even go to a physician, and therefore getting a representative sample of infected people will be all of difficult, expensive and time-consuming.

Maybe there exists a set of people who ⓐ resembles the general population and ⓑ will be tested routinely and often for years to come, such that an accurate statistical picture can be found. But I can't think of any now.

OT - how do you make those circled symbols? A tool or do you have a nice keyboard combo for it? It makes this in-line summing up of points much clearer, I like it at least at first sight.

I really like those ;) They're not as practically useful as —, ⅓, → and a few others, but I really like them. I type compose (a) to get ⓐ. See https://rant.gulbrandsen.priv.no/xcompose for how I did it, it's mostly a matter of using someone else's .xcompose file from github.
